Federal Facilities Online Academy: RCRA/CERCLA Integration - July 13, 2022, 1:00PM-3:00PM EDT (17:00-19:00 GMT).
RCRA and CERCLA Integration at Federal Facilities is a two-hour webinar course that will provide an overview of how the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) can be integrated at Federal Facilities through use of Federal Facility Agreements, regulator coordination, and lead regulator approach.
By taking this course, participants will achieve the following objectives: Learn about Federal Facility Agreements and how they identify RCRA and CERCLA roles and responsibilities; Explore relevant memos and policies addressing RCRA and CERCLA coordination; and, Become familiar with some RCRA policies that apply to CERCLA wastes.

From Superfund to Super Fun - The Benefits of Recreational Superfund Site Reuse - July 19, 2022, 2:00PM-3:30PM EDT (18:00-19:30 GMT).
Consideration of future use is an integral part of the EPA's cleanup programs.
Superfund site restoration and reuse can revitalize local economies and communities with recreational opportunities.
This webinar will showcase the benefits of recreational reuses at Superfund sites across the country.

It's All Connected - Risk Assessment through Selected Remedy - July 20, 2022, 1:00PM-4:00PM EDT (17:00-20:00 GMT).
This webinar will look at various steps of the remedy selection process, from the baseline MEC risk assessment that is conducted at the end of the Remedial Investigation (RI) through to describing the Selected Remedy in in the Record of Decision (ROD).
The topics presented will address creating risk scenarios for the Risk Management Methodology (RMM), and show how these can be used to support the development of Remedial Action Objectives (RAOs) during the Feasibility Study (FS).
Additional topics will cover the development and evaluation of remedial alternatives in the FS that achieve the RAO, and outline some best practices for describing the Selected Remedy and cleanup goals in the ROD.
The instructional methodology for this course includes lecture, case studies, and quizzes.
The target audience for this course is federal, state, and tribal representatives who work on Federal Facility cleanups.
Ideally, students should have a basic understanding of RCRA and CERCLA.
This course is part of the Federal Facilities Academy training program.
Please consider registering for other Federal Facility Academy courses and obtain a certificate upon completion of the entire Federal Facility Academy series (12 courses total).

Climate Adaptation Profiles: Solvents Recovery Services of New England.
EPA is developing a series of site-specific profiles to illustrate a range of processes and tools for evaluating site vulnerabilities to future climate scenarios and adapting to the projected scenarios, thereby assuring site cleanup remedies remain protective of human health and the environment.
The second profile release in this series describes adaptation measures taken at the 42-acre Solvents Recovery Service of New England, Inc.
Superfund site in Southington, Connecticut.
Remedial actions currently involve maintaining a multilayer cap above contaminated soil, wetland soil and river sediment and continuing extraction of contaminated groundwater for ex situ treatment.
The site is vulnerable to flooding and associated soil erosion due to its location along the Quinnipiac River.
Climate adaptation measures have included constructing an infiltration gallery to manage stormwater, reestablishing native vegetation in wetlands and upland areas, and encasing groundwater extraction controls in water-resistant housings.
An onsite renewable energy system above the cap powers the site's groundwater extraction pumps and a supporting building, which produces a climate change adaptation and mitigation synergy that provides energy resilience and diversification while minimizing emission of greenhouse gas.

Climate Adaptation Profiles: American Cyanamid Co.
The third release in EPA's series of climate adaptation profiles describes measures taken at the 435-acre American Cyanamid Superfund site in Bridgewater, New Jersey.
Remedial actions currently involve operating a groundwater extraction and treatment system, designing multiple soil or waste capping systems, and planning excavation of other waste to be treated offsite.
The site is extremely vulnerable to flooding; most of the site is located with a 100-year floodplain of the Raritan River.
The site also experiences periodic flooding due to tropical storms associated with hurricanes strikes along the U.S.
East Coast.
Climate adaptation measures have included constructing a groundwater treatment plant at a location outside the 500-year floodplain, installing submersible pumps in bedrock wells to maintain hydraulic control during flood-related power outages, and designing the capping systems to withstand a 500-year flood event.
The remedies' resilience to flooding was reassessed in 2021 after the site experienced a tropical storm associated with Hurricane Ida, and the results indicated no major physical damage, groundwater treatment interruption, or surficial release of contaminants had occurred.

Superfund Research Brief 330: Study Sheds Light on Breakdown Products of PCBs in the Environment.
NIEHS Superfund Research Program (SRP) grantees discovered toxic breakdown products of polychlorinated biphenyls (PCBs) in contaminated sediments at proportionally higher levels than found in commercial PCB mixtures.
According to the team, these findings point to environmental processes, such as metabolism by animals, plants, or bacteria, in generating the harmful chemicals.
PCBs are persistent environmental pollutants classified as human carcinogens.
From 1930 to 1979, PCBs were manufactured as mixtures of individual PCB compounds called Aroclors.
Although PCBs were banned in 1979, they still persist in air, water, soil, and sediments, and are still produced as byproducts of some industrial processes.
